Matter is anything that has volume and has mass. Mass- A measure of the amount of matter in an object. Volume-The amount of space that an object takes up. Metric Units. Meter Measures Length. Liter Measures Volume. Gram Measures Mass. m. ml or cm 3. g. L x W x H = cm 3
ml or cm3
L x W x H = cm3
Common Length Units in
Most Common Volume Units in Metric System
Density = mass/volume
UNITS- g/ml or g/cm3

Using a Triple Beam Balance
The balance has three beams called rider beams. Each rider beam has a different mass suspended from it. These masses, called riders, can be moved left and right along the rider beams. By moving the riders, you can determine the mass of an object placed on the measurement tray.
An adjustment knob is used to calibrate the balance. When no objects are sitting on the measurement tray, and all the riders are in their leftmost or 0 position, the pointer should be lined up with the zero mark. If it is not lined up with the zero mark, you would need to turn the adjustment knob until it is.
To find the mass of an object using a triple beam balance, place the object on the measurement tray and adjust the positions of the three riders on the rider beams until the pointer lines up with the zero mark. The mass of the object can then be found by adding the values indicated by the three riders.
